  • Adrian Castro, MD, FAAP

    "Becoming a Pediatrician allowed me to combine my interest in science with my fascination for watching the natural curiosity and love of the world that children and adolescents have. Everyday I walk into our exam rooms happy to care for my patients. I work diligently to be a partner to parents, providing them with direction and support to ensure their children recover from illness, stay healthy, and reach their full potential. Being a parent of two has made me realize how heart-wrenching it can be to ever see your little ones suffering. So I have become so much more empathetic to parents who sometimes need reassurance that their children will be ok, or need just a hand to hold when things are going to be challenging. When I’m not in the office I enjoy playing with my two kids, exploring new music or new cuisines with my wife, traveling with my family to experience new places and cultures, watching movies, and reading. I am also very passionate about advocating for social justice reform and try my best to make time to volunteer to help those less fortunate. I am honored to care for your little ones.” For more information on Dr. Castro, please click on his link.

    “I believe listening to a patient’s story is vital to successfully diagnosing and treating illness. I also believe preventative care goes a long way, so I spend a lot of time educating both parents and children about how to take care of their bodies, physically and emotionally. I have three children and together with my husband we keep our family healthy by eating well, sleeping as much as possible, and exercising through activities that we enjoy doing. When not in the office I enjoy reading, cooking, staying active through running and yoga, and spending time with my family; movie nights at home are a favorite of mine. I am honored to build a relationship of trust and understanding with my young patients and their parents.” For more information on Dr. Chou, please click on her link.

  • Diala Faddoul, MD

    “I treat my patients like family. I make myself available to them as much as possible to help them through the challenges of staying healthy. I’ve learned a lot raising my own two children and being a parent has helped me truly understand the concerns and fears that parents have when their little ones are ill. I try to quell those fears as much as possible through education and sharing my own experiences as a parent. I practice healthy habits with my husband and two children by hiking or going on walks regularly, and eating healthy meals. When not in the office I enjoy playing the piano, playing tennis, and reading. I enjoy making a positive difference in my patients’ health and improving the quality of their lives."

    “On my desk is a framed school assignment from the 2nd grade explaining why I wanted to be a doctor. I always did, especially since I loved my own pediatrician as a child. My wife and I have a son affected by autism; he was another big reason why I chose to pursue pediatrics. Observing and participating in his care has greatly informed my approach to medicine. I practice evidence-based care, eliminating unnecessary or unhelpful treatments. I listen carefully to both my patients and their parents to uncover the issues and treat any illness effectively. I also believe that the mind has a powerful influence on health and well-being so I strongly promote mental health. I encourage everyone to be curious about life, and balance work/school with a variety of interests. When not in the office, I enjoy constructing crossword puzzles. A couple dozen of my puzzles have been published in the NY Times, LA Times, and other publications. I also enjoy listening to classical music, watching classic and modern film, playing with our dog, traveling with my family, and, more recently, cooking has become a hobby of mine.” For more information on Dr. Koetters, please click on his link.

    “Communication is the key to practicing good medicine. I like to make sure parents and my patients (when old enough) understand their illness and how best to treat it. I love getting to know my families more and more over time, which makes the entire working relationship better for everyone. Being a parent has helped me relate to the families I care for. It’s fun to share stories of my own experiences that let parents know I truly understand their concerns. When not in the office I enjoy going to the gym, playing the drums, and being outdoors including mountain climbing and hiking. I love spending time with my two sons traveling, going to sports events, building Legos, and hiking. I am also a Reserve Deputy Sheriff on the Montrose Search & Rescue Team, a “White Suiter” for the Tournament of Roses, and I work with the non-profit group, Healing Hearts Across Borders. Some of my favorite experiences have been having some of my former patients volunteer alongside me with that group in Mexico. I truly enjoy helping people live a healthy life.” For more information on Dr. Rodarte, please click on his link.
